Is it true that a school bus may only be operated at 55 mph on an interstate highway?

A school bus is not strictly limited to a maximum speed of 55 mph on an interstate highway; therefore, the statement is false. In Texas, the speed limits for buses can depend on several factors including the posted speed limits on the interstate and specific regulations governing school bus operations.

Typically, school buses are required to adhere to the same speed limits as other vehicles, which may be higher than 55 mph in certain areas. Additionally, conditions such as weather, traffic, and the specific roadway signage play crucial roles in determining safe and legal speeds for bus operation. This context reinforces that while there may be guidelines, the regulation of speed is more nuanced than a blanket restriction of 55 mph on interstates.
